Subject: [PATCH RFC 0/5] Add IRQC support to RZ/G2UL SoC

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Hi All,

This patch series does the following:
* Adds IRQC support to the RZ/G2UL SoC.
* Includes a fix for pinctrl driver when using GPIO pins as interrupts
* Adds PHY interrupt support for ETH{0/1}

Reason for sending it as RFC, as I am introducing new compatible string for
RZ/G2UL SoC as there are some differences when compared to RZ/Five:
- G2UL IRQCHIP (hierarchical IRQ domain) -> GIC where as on RZ/Five we have
  PLIC (chained interrupt domain) -> RISCV INTC
- On the RZ/Five we have additional registers for IRQC block
- On the RZ/Five we have BUS_ERR_INT which needs to be handled by IRQC

Cheers,
Prabhakar
